摘要：

通过实验研究了润湿性对采收率及相对渗透率的影响,还研究了利用原油老化控制岩石润湿性的方法。结果表明弱水湿岩石水驱采收率最高,亲水岩石油相相对渗透率高于亲油岩石,原油中极性物质的吸附会影响岩石表面润湿性,油湿性随老化时间增加而增强。

关键词: 润湿性, 水驱采收率, 相对渗透率, 老化时间

Abstract:

The effect of wettability on recovery and relative permeability by waterflood test and the method of controlling rock wettability by aging crude oil are studied in this paper.The results show that waterflood recovery of weak water-wet rock is the highest;the oil relative permeability of water-wet rock is higher than that of oil-wet rock;the adsorption of heavy polar materials in crude oil can effect the wettability of rock surface and oil-wet may be ehanced with the increase of aging time.

Key words: wettability, waterflood recovery, relative permeability, aging time
